CRANK AND LEVER.

specification of Letters Patent.

Patented July 5, 1915..

To all whom t may concern Be it known that we, LOUIS D. Knrswn'r- 'runand lVrLLIAM S. ROBERTS, citizens 0f the United States, residing atDenton, in the county of Doniphan and State of Kansas, have inventedcertain new and useful improvements in Cranks and Levers, of which thefollowing; is a specification, reference being had to the accompanyingdrawings.

rllhis invention comprehends certain new and useful improvements incranks and levers and has for a primary object to provide novel andimproved means for con verting rotary movement into reciprocatorymovement.

Another object is to provide mechanism of this character which will beof extremely simple construction and highly efficient and effective inuse.

lVith the above and other objects in view, this invention consists inthe novel features of construction, combination and arrangement of partsas will be hereinafter more` particularly set forth in thespecification, pointed out in the claim and illustrated in theaccompanying drawings, which form a part of this application and inwhich,

Figure 1, is a side elevational view of an embodiment of our inventionapplied to a pump of ordinary construction. Fig. 2, is a frontelevational view of the arrangement shown in Fig. 1. Fig. 3., is a topplan view of the upper portion of the invention as herein disclosed.

Referring more specifically to the drawings, in which similar referencecharacters designate correspon ding;r parts throughout the severalviews, 1 indicates the base which is formed in sections positioned uponopposite sides of a pump 2 and above the platform 3. each section havinga semi-circular recess 4 formed in one side to accommodate the pump 2and the sections 1 being' clamped together by the clamp bolts 5 or othersuitable means. l

One of the sections 1 is considerably longer than the other section andproiects bevond the 'platform 3, the purpose of which will presentlyappear. This section 1 is braced bv means of the bra cine.` bars 6 whichhave their opposite ends bent` ask shown at 7, one of the bent ends ofeach bar 6 beine; secured upon the platform B while the other is securedto the long member 1 near its projected end.

Suitable bearing members 9 are provided upon the opposite ends of theupper face of the long member 1 to receive the crank shaft 8 and supportthe same above said long member 1, the ends of the shaft project ingbeyond the base member 1 and one projecting end of the shaft being bentto form the crank portion 10 while the drive wheel 11 is secured uponthe opposite end of the shaft. The shaft 8 is also provided with acentral crank portion 12, the purpose of which will presently appear.

Secured to each of the crank portions 10 and 12 of the shaft 8 are thelower ends of the pitman rods 111. The upper ends of the pitman rods 14:are connected by the arcuate connecting member 15 which has a verticalcentral opening4 to receive the reciprocating member 18 of the pump. Theopposite ends of the arcuate member 15 are connected with the upper endsof the pit-man rods 14.- by bolts 16 or other suitable means. Thecentral upwardly extending collar 13 is provided upon the arcuate member15 around the central opening of the latter and the transverselyextending pin 17 is positioned through this collar and through thereciprocating member 18 of the pump. Thus it will be seen that as thedrive wheel 11 is rotated by suitable power. to rotate the shaft 8. thepitman rods 14 are operated to move the arcuate member 15 and thus raiseand lower the pin 17 to reciprocate the reciprocatinnr member 18 of thepump 2.

While we have shownthe preferred embodiment of our invention. it will beunderstood that we do not wish to be limited to this exact form, asminor changes in the details of construction mav be made within thescope of the appended claim without departing from the spirit of ourinvention.

Having thus described our invention, what we claim is A device of theclass described comprising the combination with a pump including areciprocating pump rod, of a cross head having a central opening toaccommodate the reciprocating pump rod while the opposite ends of saidcross head are directed downwardly, said cross head being also providedwith a lateral sleeve aroundthe central opening and adapted forengagement around the reciprocating pump rod and dis- In testimonywhereof we hereunto affix 10 posed in a direction away from the pump,our signatures in the presence of two wita pivot member extended throughsaid nesses.` sleeve and reciprocating pump rod, pitman rods rigidlyconnected with the extremities LOUIS D' KEISWETTER' of the Cross head,and a crank shaft pro- 'WILLIAM S' ROBERTS' vided with operating means,said pitman Witnesses: rods being operatively engaged with the C.
